Consider a completely elastic head-on collision between two particles that have the same mass and the same speed. What are the velocities of the particles after the collision?

The magnitude of their velocities will be the same but their direction will be reversed.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
